CodeSystem: Space Exercise Performance Metric Code System

Official URL: http://hl7.org/fhir/uv/aerospace/CodeSystem/space-performance-metric-cs Version: 0.5.12
Active as of 2026-03-25 Computable Name: SpacePerformanceMetricCS

Key performance metrics for space-based exercise sessions (e.g., power output, VO2 surrogate, effective ground reaction force).

This Code system is referenced in the content logical definition of the following value sets:

This case-sensitive code system http://hl7.org/fhir/uv/aerospace/CodeSystem/space-performance-metric-cs defines the following codes:

CodeDisplayDefinition
mean-power Mean power output Average mechanical power output over the activity interval.
peak-power Peak power output Maximum mechanical power achieved during the activity.
simulated-bw Simulated body weight Effective body-weight load, typically as a fraction of 1-g weight, during harness or artificial gravity exercise.
total-work Total mechanical work Total work performed across the activity interval.
vo2-surrogate VO2 surrogate index Computed surrogate for oxygen uptake based on HR, power, and subject parameters.
recovery-hr 1-minute recovery heart rate Heart rate recorded one minute after cessation of exercise.
hr-reserve-percent Percentage heart rate reserve Intensity expressed as % of heart rate reserve.
ground-reaction-force Ground reaction force Effective ground reaction force during treadmill exercise with harness loading.
resistance-level Resistance level setting Resistance setting on exercise equipment.
cadence Exercise cadence Steps per minute (treadmill) or revolutions per minute (cycle ergometer).
